NL100/105 Network Link Interface
3
The RS-232 should be a standard straight through cable. It is
recommended that the cable be kept at lengths of
≤
6 feet to maintain high
data throughput rates.
The CS I/O 9 Pin cable is a straight through cable with all 9 pins
connected. Campbell Scientific’s SC12 cable is recommended.

this product may cause radio interference in which case the user may
be required to correct the interference at the user’s expense.
2. Setting up the NL100/105 for Communication
The NL100/105 must be set up by configuring one or more of the
communications ports for communication with your datalogger or other devices
in the network. To do this, you must establish a direct communication link with
the NL100/105 using a PC computer. You will need a null modem cable
between the computer and the NL100/105 and a terminal communication
software package (such as HyperTerminal, which ships with Microsoft
Windows operating system software).
2.1 Computer to NL100/105 Physical Connection
An RS-232 null-modem cable is required to establish communication between
the NL100/105 and your computer. One end of the cable is connected to the
computer's 9-pin RS-232 communications port and the other end is connected
to the RS-232 port of the NL100/105. If the null-modem cable does not have a
female connector on both ends, you may also need a female-to-female adapter.
For additional information on null-modem cables, refer to Appendix B.
The NL100/105 requires 12 VDC for operation. This power source can be
supplied by the datalogger's 12 V supply or by a regulated external power
source. When connecting the power leads, the ground lead should be connected
first and then the 12 V lead.
